Uponor MLC Press-Fit: The Multi-Layered Plumbing System

MLC Press-Fit: The multi-layered plumbing system with multiple benefits

MLC Press-Fit is the most widely used alternative to copper piping in the UK market place because it's faster, cleaner, more cost-effective and more secure. Consequently, there's no better way to fast-track efficiently executed, watertight plumbing installations.

MLC is just like copper... only better. It's the definitive multi-layered plumbing system with multiple benefits, and here are just a few of them:

Designed to deliver fast and clean installations

Easy to bend. Just cut to length and press to fit a guaranteed, secure connection. 'Head to head' speed tests have proved that it's faster... and easier.

Designed for fewer connections

The inherent stability of the pipe and the low linear expansion mean only a few fixing points are necessary. This delivers a highly practical advantage for a safe and fast installation.

Designed to last

It's corrosion and incrustation-free. The five-layer composite pipe has a diffusion-tight aluminium core layer that prevents the ingress of oxygen.

Designed for inherent flexibility

Perfect for any application where copper pipes might be used. Used worldwide for commercial and domestic applications. Available in the widest range of sizes: 16 - 110mm.

Designed to make 'your life easier'

It's not only simple, easy and fast to use... MLC Press-Fit also offers the full support and extensive back-up that you'd expect from a major brand and market leader. Training, comprehensive instructions, and technical advice are available.

The MLC Press-Fit pipe: 5 layers - built for the future

With our 5-layer composite pipe, Uponor has developed a product with a future, which combines the benefits of both metal and plastic pipes. Product benefits are obtained that cannot be surpassed: The inner aluminium layer provides a 100% oxygen-proof barrier. It compensates for the snap-back forces and the linear expansion caused by temperature changes. The basis of the system is simple, safe, and fast pipe installation: simply bend by hand, cut to length, bevel, join together, press - done!

The Uponor MLC Press-Fit pipe consists of a longitudinal safety overlap welded aluminium pipe, to which an inner and outer layer of high-temperature resistant polyethylene is applied (in accordance with DIN 16833). All layers are permanently bonded together by means of an intermediate adhesive layer. A special welding technique guarantees a maximum of safety. The thickness of the aluminium selected for the Uponor MLC Press-Fit pipe is exactly adapted to the compressive strength requirements as well as the bending capability, confident that you're installing tried and tested, certified quality. Our system technology is safe and long-lasting, certified by numerous tests and licenses.

Low linear expansion

Low weight

Easy handling

The best installation: The Uponor MLC Press-Fit pipe for tap water installation and radiator connection can also be ordered pre-insulated (up to 25mm). An assortment is available in sizes from 16-110 mm. The pre-insulated pipes save installation time because the time-intensive insulation of the mounted pipes and the resulting gluing of joints are eliminated.

Make the right connections

All the fittings you'll ever need

Uponor can supply the right fitting, even for complex applications. Different fitting concepts, same high levels of flexibility and quality. What else would you expect from the market leader?

MLC Press-Fit: Our Standard Fitting

Our patented press system means that fittings can be fitted incredibly quickly. Say goodbye to welding and soldering... say hello to Uponor.

• Firmly fixed press sleeve, permanently connected with the fitting body, protects against mechanical damage to the O-ring.
• Press sleeves with inspection windows allow the penetration depth of the pipe into the fitting to be checked before pressing.
• Coloured stop rings that break off during pressing (16 to 32mm).
• After installation, the form-stable press sleeve allows the connection to absorb bending forces without developing leaks. This allows a pipe that has already been installed to be realigned after installation (up until the pressure test).

Colour coded diameters: 16, 20, 25, 32, 40, 50

MLC Composite: The economy version of our Standard Fitting

During installation, the MLC Press-Fit Pipe is pushed between the supporting sleeve and stainless steel press sleeve, and a force-closed connection is made with the MLC Composite fitting. Pressed into the inner plastic layer of the pipe, the special profile of the PPSU insert produces a reliable connection. A high-temperature and age-resistant O-ring fitted into a groove provides sealing between the insert part and the inner wall of the pipe.

After installation, the form-stable press sleeve allows the connection to absorb bending forces without developing leaks. This allows a pipe that has already been installed to be realigned after installation (up until the pressure test).

MLC Click-Fit: RTM™ Technology

Uponor's RTM™ Technology: Ring Tension Memory with the Tool-Inside concept, ideal for refurbishment and new buildings, allowing safe, quick, and professional joints, thanks to the Joint Indicator and no tool dependence. RTM™ Technology works perfectly with Uponor's MLC Press-Fit pipes.

It is easy to install due to its revolutionary RTM™ Technology, a technology that has allowed Uponor to incorporate the Tool-Inside: The Ring with Tension Memory. This revolutionary RTM™ Technology creates constant pressure, ensuring perfect and long-lasting joints.

Colour coded diameters: 16, 20, 25, 32

Uponor's Modular System

Uponor's MLC Modular Fittings Range is fast becoming the system of choice on many world-class projects. With just a small range of easy-to-install fittings, hundreds of connection possibilities can be created.

The distinctive "click and lock" mechanism removes the need for overhead pressing, allowing faster install times.

Your benefits:

• Components with hundreds of fitting variations possible.
• Greater flexibility and lower logistics costs thanks to a minimal number of system components.
• Optimum availability with less storage space and lower investment costs.
• Quick to install and can be pressed at the workbench.
